VIOLIN BOW.

Application filed October 6, 1920.

To all whom it may concern.-

Be it known that I, JOHN STADNICZEK, a citizen of the United States of America, residing at Elizabeth, in the county of Union and btate of New Jersey, have invented certain new and useful Improvements in Violin Bows, of which the following is a specification.

This invention relates to certain new and useful improvements in bows for stringed instruments such as violins and cellos and has particular reference to the mounting of the ends of the group of horse hairs or other playing strings in the frog and tip of the violin bow frame.

The invention further contemplates a novel construction of frog and tip for a violin bow wherein the ends of the horse hairs are secured together and received in sockets in the frog and tip through side slots formed therein with means for retain ing the assembled ends of the horse hairs within the slots in the frog and tip.

lVith the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts throughout the several views.

In the drawing, whereln like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a side elevational view, partly in section of a violin bow constructed in accordance with the present invention,

Figure 2 is an edge elevational view of the bow,

Figure 3 is a cross sectional view taken on line IIIIII of Fig. 1 showing the grouped horse hairs of the bow within a socket in the bow frog.

Figure 4 is a perspective view of one of the side plates of the bow frog removed therefrom. showing the side entrance slot in the side plate,

Figure 5 is a perspective view of the sliding plate removed from the bow frog for retaining the horse hairs therein.

Figure 6 is a perspective view of the ferrule attached to a projecting end of the frog,

Figure 7 is a perspective view of the wedge piece entering the forward end of the frog and engaging horse hairs, and

Figure 8 is a cross sectional view taken on line VIII-VIII of Fig. 1 showing the piv- Specifieation of Letters Patent.

oted latch plate for retaining the ends of the horse hairs in the bow tip.

eferring more in detail to the accomdrawing, there is illustrated a a curved stick 1 carrylnga. tip 2 at the outer end thereof with in which the grouped outer ends of the horse hairs 3 are retained, a frog 4 being slidably associated with the handle 5 the bow and being adjustable relative to said handle by the screw piece 6 to varv the tension of the horse hairs 3. n

he bow tip 2 has a transverse slot '7 formed in the edge thereof adjacent the hairs 3, the slot 7 side wall as at 7 and opening at the opposite side wall as at 7 while the slot increases in diameter in a direction inwardlv of the outer face of the tip being of wedge shape as shown by dotted lines in Fig. 1. The hairs 3 are grouped at their outer ends and secured by a tie cord 8 with the strands thereof adjacent the tie cord introduced into the open side 7 of the slot 7 and when arranged in the position shown in Figures 2 and 8 a wedge piece 9 is inserted in the groove 7, and the plate 9 hinged upon the pin 10 at that side of the tip 2 adjacent the open side of the slot is moved from the dotted line position shown in Fig. 1 to the full line position, thus overlying the open side '7 of the slot to retain the ends of the horse hairs within the tip 2.

The bow frog 4 embodies a body portion 11 shown in F igs. l and 3 as having a circular transverse opening 12 adjacent the center and outer edge thereof with a communicating reduced edge slot 13 as shown in Fig.

In mounting the inner ends of the horse hairs 3 within the opening 12 in the body 11, the inner ends of the horse hairs are grouped as at 1 1 with the portions thereof adjacent the group inserted laterally through the reduced edge slot 13 with the enlarged grouped end thereof lying within the circular opening 12 as illustrated.

A pair of side plates 15 and 16 are secured by cross pins 17 to opposite sides of the frog body 11. lVith the outer edges thereof inwardly flanged as at 15 and 16 respectively to overlie the outer edge of the body 11. The side plate 16 as shown in Figs. 1 and 4 is provided with a. circular opening 18 communicating with a reduced slot 19 opening at the flanged ed e 16 thereof while the opening 18 and s 0t 19 are positioned for terminating short of one registration with the opening 12 and slot 13 in the body 11, thereby facilitating the within the frog 4, there is provided a sliding plate 20 shown more clearly in'Figs. 1, 2, 3 and 5 positioned within the guide flanges 15 and 16 of the side plates so that the hairs will assume relatively flat relationship between the frog 4: and tip 2. A wedge piece 21 is then inserted between the plate and the adjacent hairs as shown in Figs. 1 and 2 to hold the hairs at this point relatively immovable, while the tension on the hairs is regulated by the screw piece 6. A ferrule orthimble 22 of the form shown in Fig. 6 encloses the adjacent end 11 of the frog body 11 and the adjacent end of the plate 20 to securely bind the several parts to ether.

rom the above detail description of the invention it is believed the construction and operation thereof will at once be apparent, it being noted that the opposite ends 8 and 14: are introduced into the tip and frog respectively by lateral movement through the slots and openings as previously described while the plate 20 flattens the hairs in the head with the wedge securing the same rigidly mounted. The adjusting screw 6 will regulate the tension upon the hairs 3 to the desired point, and the complete bow is then ready for use; 7

While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is 1. A bow of the type described for stringed instruments comprising a bow stick, a frog and tip carried thereby, horse hairs at the opposite ends thereof laterally received in the frog and tip, means carried bythe tip for retaining the adjacent ends of the horse hairs therein, said frog having a side opening slot to permit the lateral reception of the horse hairs, and a sliding plate carried by the frog engaging the outer faces of the horse hairs and closing the pater end of the side opening slot of the rog.

2. A bow of the type described for stringed instruments comprisinga bow stick, a frog and tip carried thereby, horse hairs at the opposite ends thereof laterally received in the frog and tip, means carried by the tip for retaining the adjacent ends of the horse hairs therein, said frog having a side opening slot to permit the lateral reception of the horse hairs, a sliding plate carried by the frog engaging the outer faces of the horse hairs, and closing the outer end of the side opening slot of the frog, and a wedge piece entering the forward end of the frog beneath the horse hairs and sliding plate for retaining the horse hairs rigidly mounted.

3. A bow of the type described for stringed instruments comprising a bow stick,

a frog and tip carried thereby, horse hairs at the opposite ends thereof laterally received in the frog and tip, said tip having a side opening slot therein to permit the re ception of the adjacent ends of the horse hairs, a hinged plate carried by said tip adapted to be moved to a position overlying the open side of said slot to retain the horse hairs therein, said frog including a body portion with a transverse opening therein having a reduced slot extending to the ad-v jacent edge of the frog, side plates carried by said frog and overlying said opening and slot in the frog, one of said plates having an opening therein of like configuration to the opening in the frog to permit the lateral reception of the adjacent ends of the horse hairs, the outer edges of said side plates being flanged inwardly, a slide plate received within said flanges, a wedge piece positioned beneath said horse hairs, and a ferrule en- 7 closing the adjacent end of the body portion of the frog, the wedge piece and adj acent end of the plate.

In testimony whereof I aflix my signature.

JOHN STADNICZEIQ.
